Tóm tắt
The water states of poly(styrene sulfonic acid) (PSSA) grafted poly(ethylene-co-tetrafluoroethylene) copolymers (ETFE-PEMs) with grafting degree (GD)=8.8-30.5% are investigated under ambient conditions by using FT- IR analysis. Detailed analysis of the FT-IR spectra of ETFE-PEMs allows the observation of each component of water in the two broad bands of 1500-2000 cm-1 and 2400-3800 cm-1.
